1 Claim.

This invention relates to an improvement in index or record cards or sheets.

An object of the invention is to so treat record cards as will permit use of the same colored stock, for attaining the advantages incident to the use of record cards of diiierent colored stocks.

Another object is to provide an article of the above character the treated portion of which will readily receive written or typewritten matter and upon which portion said matter will be readily legible.

Another object is to provide a card filing means wherein the space resulting from removal of a [5 card will be rendered plainly apparent, thereby facilitating proper replacement of the removed card.

In the drawing, Fig. 1 is a plan view of an index card or sheet of the invention.

Fig. 2 is an enlarged fragmental view of one corner of the card or sheet.

Fig. 3 is a fragmental plan view of a tray of overlapped cards of the invention.

In Fig. 1 is shown an index card or sheet 5, along one edge 6 of which is secured a rod or bar '7 having bearing ends 8 and 9, for pivotal mounting of the card in a suitable card support or tray 20. The particular type of card exemplified herein is adapted to lie beneath other cards of a system wherein only the lower or free marginal area 10 is exposed as shown in Fig. 4. It will be understood, of course, that when the card is moved through a half circle about the axis of rod 7, the treated portions therefore may be provided. on opposite sides of the card or sheet. While the invention herein is particularly adapted to use with overlapping cards arranged as shown in Fig. 3 it will become apparent that the invention is applicable also to other types of cards having areas that may be exposed for various purposes.

The invention consists in applying, to the marginal areas of cards or sheets, a series of dots or marks as indicated at 12. This produces an area 10 which contrasts with the body of the card 5, but which will conform in color effect with adjoining overlapping treated margins and with such other margins produces a pleasing appearance because of such uniformity of color. The dots or markings producing the darkened or shaded effect should be spaced suffioiently so that written or typewritten matter applied thereon will contrast sufliciently to render such matter legible. It will readily be understood that the darkened or shaded area 10 may extend across the card or sheet, or it may extend only part of this distance, depending upon the type of system in which the card or sheet is used.

When it is necessary to provide cards 5 with 50 marks or characters, for example, dividing lines 15, these marks or lines may be applied during the same printing operation in which the shading is applied. By using the dot method of shading, a comparatively dark color of ink, suitable for lines 15, will be suitable also for the shading. The distance between the adjacent dots or marks shown in Figs. 2 and 3, may approximate one sixty-fourth of an inch. The dots or marks above referred to may be given different spacings, for the purpose of difierently marking the cards to visibly indicate different facts. It is thereby rendered unnecessary to provide cards of differently colored stock and differently colored ink markings, to secure the proper contrast therebetween.

When the invention is applied to the exposed marginal areas of overlapping cards, as illustrated in Fig. 3, the absence of one or more cards of the group may readily be detected because of the contrast between the treated areas 10 and the then exposed body portions of cards 5. The openings 16 formed in the side members 17 of the tray, provide for the insertion and removal of the rods 7 to which the cards are secured.

What is claimed is:

The combination of a tray for removable mounting of record cards, and record cards mounted in overlapping relation so as to expose 90 to view a marginal portion of each record card, the cards each having spaced dots upon its exposed portion for eiiecting contact between the exposed portions and the overlapped portions of such cards, the dotted areas each providing a back-ground upon which written matter may be legibly applied.
